Desculpem o cross-posting, mas acredito que alguns aqui podem ter interesse em estudos com este novo recurso disponível para o FreeBSD, principalmente na área acadêmica.
---------- Forwarded message ---------- From: Lawrence Stewart <[EMAIL PROTECTED]> Date: 19/12/2007 05:54 Subject: [e2e] Modular/Pluggable TCP Congestion Control for FreeBSD To: [EMAIL PROTECTED] Hi all, We've been involved in a research project to implement and test an emerging TCP congestion control algorithm under FreeBSD. As a part of this, we've put together a patch for FreeBSD 7.0-BETA4 that modularises the congestion control code in the TCP stack. It allows for new congestion control algorithms to be developed as loadable kernel modules. This improves FreeBSD's usefulness as a TCP research platform and makes it easier to customise the stack for specific scenarios like high bandwidth, long delay paths. There is an accompanying technical report "Light-Weight Modular TCP Congestion Control for FreeBSD 7" [1] that covers the design, features, kernel interface and usage of the framework. Also on our website is a beta release of a module that implements the H-TCP[2] congestion control algorithm proposed by the Hamilton Institute. We believe that modular congestion control is a worthwhile addition to FreeBSD. We've performed significant internal testing and there are currently no known issues or regressions with the implementation compared to a 'vanilla' FreeBSD 7.0-BETA4 kernel. We would welcome further review and testing from the wider community in the hope of getting this patch folded into FreeBSD 8-CURRENT. SIFTR [3], our tool for monitoring FreeBSD kernel TCP connection state, has also received a minor update to v1.1.5, with the addition of 6 new, useful variables. All code and documentation is available on our website[3].
